WHEEL-SPOKE To all whom 2'6 may comic m it known that l, Renonr Knosnnnnno, subject of the King of Prussia, residing at Qhligs, in the Province of the Rhine, Kingdom ot' Prussia, German Empire, have invented certain new and useful improvements in lVheel-Spoke Stars, of which the following is a specification.

This invention relates to a wheel spoke star with stillening' supports secured in a wood ring.

In the case of pressed wheel spoke stars, which as is well known, are composed of two parts, the inner ends of the hollow spokes have proved of insullicient resistance. The power of resistance, however, may be increa sed by inserting in the inner end of ea h hollow spoke a stiffening bar which is fixed at a right angle to the plane or the wheel. The fastening oi such a stiffening bar to the side walls of the spoke star involves certain ditliculties. According to the present invention, the stitjening bars are therefore liXed with their inner ends in a common wood ring. In the drawing, such a star provided, with these stiffening bars, is illustrated in Figure 1 on a small scale, whereas in Fig. 2 is shown section across the wheel axle through a portion of Specification of Letters late'nt.

the star and in Fig. 3 an axial section through the same portion with partial elevation.

The spokes are indicated by (l, and the stiffening radial bars by 7). Each bar Z) is inserted with its inner end in the common wood ring This can also, moreover be wrapped with a wire (Z as shown in order to azl'ord a still firmer hold for the whole construction.

Raving now particularbdescribed and ascertained the nature of my said invention and in what manner the same is to be perforn'ied, l declare that what 1 claim is it spoke slur comprising hollow spokes formed in two members, each spoke having outwardly curved inner ends nested together with the corresponding ends of adjacent spoke:., a wooden ring between the opposite sides of said spokes and radial bars in said ring projecting outwardly between the curved ends of said spokes.

ln testn'i'iony, whereof I have signed my name to, this specification in the presence of two subscribing witnesses.
